I've been leaning towards getting one of those shnazzy graphics they sell for rear truck windows with all sorts of different designs available - I mean, being that a Fox notch has just about the same basic dimensions as a rear full-size truck window (with an added curve to it). There's a groovy old-school Air Force type logo with Bettie Page laying on it that I've really been giving the eye, but I do recall also seeing some Jolly Roger style graphics and a lot of others you might be interested in.
They don't kill visibility from the inside, as they're perforated with a bajillion little holes to see through, but they make it almost impossible for anyone to see inside your car from the outside. They do block a decent amount of sunlight/heat from coming in, too. I'm not sure if they apply to the inside or outside surface of the glass. JC Whitney and Summit Racing both have a slew of them for sale, and I'm sure you could find 'em on eBay or some other places, as well - heck, even Autozone can get a lot of 'em. They run anywhere from $80 to $120, depending on the size and style and such.
Just something you might consider. Y'know, kill two birds with one stone instead of doing separate tint and graphics applications.
